IMPROVEMENT lN ELASTIC TYPE FOR PRINTING ON IRREGULAR SURFACES.

Specification forming part of Letters Patent No: 9,91 l, dated August 2, 185

To all whom it may concern:

Be it known thatI, J ULIUs HERRIET, of the city, county, and State of New York, have invented a certain new and useful Elastic Type- Plate for Printing on Irregular Surfaces, and on smooth but hard surfaces, such as glass, wood, plaster, oil-cloth, &c; and I do hereby declare that the following is a full, clear, and exact description of the same.

The nature of myiuvention consists in forming letters, figures, or other characters or figprocess of stereotyping, I then take three parts,

by weight, of the best Coopers glue and two parts of molasses and thoroughly mix them together at the requisite degree of heat, in the same manner as when employed for making inking-rollers for printing-presses, and when sufficiently baked I pour it into the mold, and

when cooled it is taken out. be found -to have taken a complete impression of the mold with all the characters in relief. The substance thus produced will be found to be highly elastic, and to hold and impart any of the known kinds of printers ink, and from its elasticity impressions can be made on irregular and uneven, or smooth but hard surfaces with facility.

The figures or characters in relief I usually raise to a greater extentthan in making stereotype-plates of metal, particularly when intended for printing on very uneven surfaces. The said plates can be made to vary in the degree of elastic tension by varying the relative proportions of glue and molasses, as is well known to those who make inking-rollers.

What I claim as my invention, and desire to secure by Letters Patent, is-- Making, by casting in molds or by pressure, plates with raised characters or figures, the entire substance of such plates being sufficiently elastic as to adapt it toprinting, substantially as described.

JULIUS HERRIET.
